More simulations to downscale CMIP5 GCMs future projections for the Arctic CORDEX domain are planned. Focus will be on RCM simulations for the RCP8.5 scenario. We will discuss and plan these simulations with the goal of having a good RCM-GCM matrix, i.e. the groups will try to run their RCM with at least two different GCM forcings.

We will also seek ways to strengthen our link to the Arctic Council “Adaptation Actions in a Changing Arctic” (AACA) project. The AACA project looks at future climate impacts, their interactions with other non-climate and socio-economic drivers of change, and the relevance of this for designing adaptation policies. We want discuss which Arctic CORDEX results and analysis are relevant for and should feed into the upcoming AACA report.

Discussion session on downscaling CMIP5 GCMs for future projectionsIntroduction by Torben KoenigkEach modeling group should give a short presentation on the status and plans of their GCM-driven Arctic CORDEX simulationsPresentations from SMHI-RCA4/RCAO, AWI-HIRHAM5, DMI-HIRHAM5, UniColo/ISU-WRF/RASM, BCCR-WRF, MGO-RRCM, UTrier-CCLM, UQUAM-CRCM

By plane

The closest major city to Potsdam is Berlin, which has two airports: Tegel (TXL) and Schönefeld (SXF). From any of these airports, Potsdam can be reached by public transport (see below).

Tegel (TXL) airportFrom Tegel (TXL) airport take bus line X9 or 109 to station ‘Zoologischer Garten’ in Berlin, follow the signs to the regional train station, then take the regional train RE1 to Potsdam main station (‘Potsdam Hauptbahnhof’).

Schönefeld (SFX) airportFrom Schönefeld (SFX) airport take the regional train RB 22 to ‘Potsdam Hauptbahnhof’. Alternatively, take the suburban train (S-Bahn) line S9. Change trains at station ‘Westkreuz’, from where the S7 goes to "Wannsee". Change there a second time and take the S1 directly to ‘Potsdam Hauptbahnhof’.

By train

Most regional fast trains bypass Potsdam on their way to Berlin. Generally, we recommend getting off at station ‘Berlin Hauptbahnhof’ and taking the regional train RE1 to ‘Potsdam Hauptbahnhof’ (Potsdam main station), which takes approximately 20 minutes.

TicketTo get to Potsdam from Berlin main station, you need an ABC Ticket (3.20 Euro) which you have to get stamped on the platform.

How to get to the Research Unit in PotsdamThe Research Unit Potsdam of the Alfred Wegener Institute is located at Telegrafenberg, the historic science campus ‘Albert Einstein’, south of Potsdam city centre. From the railway station ‘Potsdam Hauptbahnhof’, a 20 minute walk takes you to the campus at Telegrafenberg. Alternatively, a taxi takes less than 5 minutes and costs approximately 5 Euro. Local public transport in Potsdam (bus and tram), does not service Telegrafenberg directly. There are two buildings of the Alfred Wegener Institute on campus. The old one (A43) is located on the right-hand side, about 50 m from the entrance to the campus, and the new laboratory building (A45) is located about 100 m left of the campus gateway.

By car

Potsdam is located just southwest of Berlin, within the ‘Berliner Ring’, a circular motorway surrounding Berlin. From nearly all directions, the simplest way to Potsdam is via the ‘Berliner Ring’ (A10), exit 17 ‘Potsdam-Süd/Michendorf’, subsequently following the road B2 to Potsdam. 600 metres past the ‘Potsdam’ city limit sign, turn right into ‘Brauhausberg’ street, also signposted for ‘Landtag’. After 1.2 km, turn right again into ‘Albert-Einstein’-street (signposted ‘GeoForschungsZentrum’), which will lead directly to the entrance of the campus.
